To all whom itmay concern:

Be it known that I, ROBERT J. S-MIRLE, a citizen of Canada, and aresident of the city and. county of San Francisco and State ofCalifornia, have inventeda certain new and useful Wire-UncoilingApparatus, of which the following isa specification.

The invention relates to apparatus for uncoiling a coil ofwire.

An object of the invention is to provide an apparatus for uncoiling acoil of wire without kinking or tangling the wire.

Another object of the invention is to provide a wire uncoiling apparatusin which the coil of wire remains stationary.

The invention possesses other advantageous features, some of which, withthe foregoing will be set forth at length in the following descriptionWhere I shall outline in full, that form of the invention which I haveselected for illustration in the drawings accompanying and forming partof the present specification. In said drawings I have sh own onespecific form of the apparatus of my invention, but it is tofbe under-'stood that I do. not limit myself to such form, since the invention,asli-set forth in the claims, may be embodied iii a plurality of forms.Referring to said drawings Figure l is an elevation of the apparatus.

Fig. 2 is a vertical section of the apparat'us.

Fig. 3 is a top cr plan view of the apparatus.

The apparatus of my invention comprises a suitable base 2, preferablymetallic, 'on

which the coilof wire 3 is laid. The base is preferably circular and isprovided at the periphery with an elevated portion or flange 4:, forminga seat on which the coil of wire is disposed. Arranged at the center ofthe base and preferably integral therewith is a stud 5, preferablyconical in shape. The coil of wire surrounds the stud which, with thebase, causes the coil to remain more or less intact.

Rotatably disposed in the stud and extending from the upper end thereofis a curved pipe or conduit 6, which is bent downward toward the coil.At its end the pipe is bent into an are 7, which ends substantiallytangentially with respect to the coil. The portion 8 of the pipe Whichis may seat within the stud or the pipe may be after become apparent.

out through an aperture 12 at the upper end of the bent pipe.

Arranged above the stud 5 is a tubular guide 13, usually a piece of bentpipe, through which the wire passes and in which the direction ofmovement of the wire is changed from substantially vertical tosubstantially horizontal or to any other desired direction. The guide 13is mounted on a suitable support 14:, which may be secured to the base2, and is movable or rotatable on the support for reasons which willherein- The inlet end 15 of the guide 13 is disposed directly over thebend in the pipe 6, so that, should the wire become tangled or kinked inuncoiling so that it will not en ter the pipe 6, the movement of thewire through the guide 13 will cause the ipe 6 to move rapidly upwardand strike t e in: let'end of the guide. This action invariably loosensthe wire and overcomes the obstruction. The pine 6 is therefore not onlyrotatable, so that the lower end thereof can follow around the coil asthe wire is drawn,

wire in the event the pipe or in entering the pipe.

hen it is necessary to place a coil ofwire on the base, the guide 13 ismoved to one side to permit the pipe to be withdrawn from the stud, thepipe is then withdrawn and the coil placed. The pipe is thenreinserted-and the guide moved back to position. The length of the pipedisposed within the stud is such that it is not entirely withdrawn fromthe stud when the pipe strikes the guide so that it falls back to itsnormal position.

I claim:

1." A wire uncoiling apparatus comprising a base, a stud arrangedcentrally on said base and adapted to be surrounded by the coil of wire,and a conduit rotatably mounted on said stud and movable vertically withrespect thereto having its lower end overlying the coil of wire andcurved forward to receive the wire as it uncoils.

2. A wire uncoiling apparatus comprising a base, a stud arrangedcentrally on said base and adapted to be surrounded by the coil of wire,

a conduit through which the wire passes rotatably mounted on said studand movable vertically with respect thereto and'a guide for the wirearranged above said conduit.

3. A wire uncoiling apparatus comprising a' base, a stud arrangedcentrally on said base and adapted to be surrounded by a coil of wire, aconduitthrough which the wire passes mounted on said stud'for rotationaland vvertical movementwith respect thereto and a ide for the wirearranged above said condult in position to be struck by said conduit asit moves vertically."

4. A wire uncoiling apparatus comprising a base, a conical stud arrangedcentrally on said base and adapted to be surrounded by the coil of wire,a bent pipe mounted on said stud for vertical and'rotational movementwith respect thereto, said pipe being bent downward So that, the endthereof is disi posed adjacent the coil of wire, said end being wire andmeans ing; curved forwardly to receive the uncoilfor limiting thevertical movement of the pipe.

5. A wire uncoiling apparatus comprising a base, adapted to receive acoil of wire, a

bent pipe through which the wire passes,

movable vertically and mounted for rotation with respect-,fto said basearranged above said coil, and means for limiting the vertical movementof said pipe.

6. A wire uncoiling apparatus comprising; a base adapted to receive acoil of wire, bent pipe through which the uncoiled wire passes arrangedfor rotation concentric with 35 said coil and for vertical movement withrespect thereto the lower end of said pipe being disposed above saidcoil and being curved forward to receive the Wire from the coil andmeans for limiting the vertical movement of the pipe. A

7. A wire uncoiling apparatus comprising a circular base having anupstanding periph' eral flange, aconical stud disposed centrally withrespect to said base and adapted to be surrounded by a coil of wire, apipe bearing in said stud and being bent downwardly so that its outerend overlies said coil, said pipe being rotatably and vertically movablewith respect to said base and being provided at 50 its upper portionwith an exit opening for the wire and a wire guide arranged above saidpipe and disposed in position to be struck by the upper portion of thebent pipe when said pipe is moved vertically.

. In testimony whereof, I have hereunto set my hand at San Francisco,California, this 26th day of February, 1919.
